Prof. Orlando Rojas
I work with my team to uncover solutions that nature may provide to fulfill our material needs, by using, sustainably, resources that we find around us, including plants, marine shells and animals as well as biomass waste. Most of our work deals with small objects (colloids), including fibers, particles or other things with shapes that are not well defined. I hope to find disruptive ways to create positive societal impacts and to better our lives. I hope you have similar interests. If you do, I am more than open to collaborate and join efforts.
Dr. Bruno Mattos
Supracolloids, controlled release
Dr. Johanna Majoinen
Supracolloids and surface functionalization
Alvaro Gonzalez Vogel
Electrodialysis in fiber lines
Structural color with CNC
In my research, I use tiny nanoparticles manufactured from a highly abundant and sustainable bio-resource, wood. They assemble into interesting nanostructures that resemble the DNA helix. Uniquely, this creates structural colour with the potential to replace conventional toxic colorants. I engineer the creation of these nanostructures to be applied as cheap coatings providing colour and durability.
Lignin carbon materials
I am a doctoral candidate in Aalto University developing advanced materail from lignin streams.
Preparation and characterization of stimuli-responsive cellulose foams
I am a doctoral candidate in BiCMat working on structured food using nanocellulose and nanochitin
